Founder also doesn't have a universal definition and by your own link the courts decided that he could be called a co-founder, along with the 4 others.
Only spacex here is a unicorn.Everything else has been acquired or listed

Only spacex is private.
Paypal doesn't even appear on the list of employers with more than 5 unicorns from ex employees I can name more off the top of my head: Tesla, Spacex, Palantir, Youtube, Linkedin, Yelp, Yammer, Affirm
